Question 1

Which plane of motion does internal and external rotation of the shoulder occur in?

Accepted Answer

Transverse plane

Answer

Internal and external rotation are rotational movements occurring around a vertical (longitudinal) axis, placing them in the transverse plane.

Question 2

What is the primary function of the pulmonary circulation?

Accepted Answer

Exchange CO2 for O2 across alveolar capillaries

Answer

Pulmonary circulation carries deoxygenated blood from the right heart to the lungs, where CO2 is expelled and O2 is absorbed before blood returns to the left heart.

Question 3

Which structure connects muscle to bone and transmits the force of muscular contraction?

Accepted Answer

Tendon

Answer

Tendons are dense, fibrous connective tissue bands composed primarily of type I collagen that attach muscles to their bony insertion points.

Question 4

An athlete performing a barbell back squat primarily engages which muscles during the concentric phase?

Accepted Answer

Gluteus maximus, quadriceps, and hamstrings

Answer

Rising from the squat position concentrically activates the gluteus maximus (hip extension), quadriceps (knee extension), and hamstrings (assist hip extension).

Question 5

Which autonomic nervous system division increases heart rate and prepares the body for physical exertion?

Accepted Answer

Sympathetic

Answer

Sympathetic nervous system activation (fight-or-flight) releases norepinephrine and epinephrine, increasing heart rate, contractility, and cardiac output.
